From a7530ef0e2e838a4a9c66ecffa9a91f492d8dc8e Mon Sep 17 00:00:00 2001 From: Ajay Kumar Date: Thu, 26 Feb 2015 20:54:45 +0530 Subject: drm/exynos: decon: Add support for DECON-EXT * Modify DECON-INT driver to support DECON-EXT. * Add a table of porch values needed to set timing registers of DECON-EXT. * DECON-EXT supports only H/w Triggered COMMAND mode. * DECON-EXT supports only one DMA window(window 1), so modify all window management routines to support 2 windows of DECON-INT and 1 window of DECON-EXT.
